46 Claims.

This invention relates to machines for use in the manufacture of 'bootsand shoes (hereinafter referred to generically as shoes) for performingwhat is known as the leveling operation.

Ihe invention is herein illustrated as embodied in a machine of thattype in which the shoe is .operated upon progressively by relativemovements of a shoe support and a leveling tool, such as a roll, indirections lengthwise of the shoe,

' 11 and-in which the relative movements are effected by power-operatedmeans continuously under control of the operator so that differentportions of the sole of the shoemay be treated selectively in the mannerdetermined by the operator in accordance with the requirements of theparticular shoe. It is to be understood, how ever, that in various novelaspects the invention is not limited to machines of that particularcharacter. I I

'An object of the invention, among others, is tov provide improvementsin machines of the above-mentioned type, to the end that shoes may bemore efiectively and satisfactorily treated than heretofore by the useof such machines, It is alsoan object to provide a machine convenientfor use'and one that may be operated and controlled with but littleeffort on the part of the operator. To these and other ends, the machineherein shown, in one important aspect, comprises novel means wherebyrelative movements of the shoe support and the leveling tool areeffected and controlled in such manner as to permit the extreme toe end'of the sole to be satisfactorily treated without any danger of excessive bending of the margin of the sole by the action of the toolthereon. In the construction shown the shoe supporter jack 'is movedrelatively to the leveling roll in directionslengthwise of the shoe bypower-operated means which is continuously under control of theoperatoras and for the purpose hereinabove described; and mechanism is providedfor imparting automatically to the roll in predetermined relation to themovement of the shoe support, movementheightwise of the shoe intoinitial engagement therewith on the bottoinface of the toe endof thesole and reverse movement finally out of engagement with the shoe fromaposition in the same relation to the .toe end of the sole. There isaccordingly no dangerof excessive bending of the margin of the toe end.of the sole by running of the roll on or off the shoe. As hereinillustrated, the roll receives its movement into engagement with theshoe prior to the first rearward movement of the shoe support (i. e.,movement of the support in a direction away from the operator), and iscarried out of engagement with the shoe only after the final forwardmovement of the shoe support, the movements'of the roll and the shoesupport being effected under control of power-driven cams shaped andarranged for the accomplishment of these results, By reason of thisconstruction the proper leveling of the toe end of the sole isfacilitated, since the operator may readily bring the machine to a stopwith the shoe support at the limit of its forward movement and the rollin engagement With-the toe end of the sole, after which he'may tip theroll laterally of the .shoe by means provided for that purpose to. shapethe toe end of the sole properlythroughout its width. To facilitate themounting of the shoe on the shoe support and its removal therefrom, theconstruction shown is also such'that the roll is moved'lengthwise of theshoe in forward and rearward directions simultaneously with itsmovements heightwise thereof as above-described, so that it is'wellretracted from over the toe end of the shoe prior to and after theleveling operation; and in this aspect a novel feature of the inventionis further to be recognized in means for imparting to the leveling toolpositioning and retractive movements lengthwise of the shoe.

As a further feature, the invention provides novel means whereby theleveling tool may be controlled by the operatorin such manner as toapply theleveling pressure selectively to one or more portions of, theshoe bottom Without pres- Q sure onother portions or to vary the amountof pressure applied. As herein illustrated the leveling roll is presseddown upon the shoe bottom by power-operatedmeans including a rodconnected to'a vertically swinging carrier that supports the roll, andfor the purpose in view there is provided. 'treadleoperated mechanismarranged to act through this rod to support the roll or lift it from theshoe at any time when the operator so desires. I

Facility in the control of the machine is further afforded, in :theconstruction shown, by the provision of hand-operated members atopposite sides of the machine, one for controlling the power operationof the machine and the other for tipping the roll laterally of the shoe,combined with means whereby the roll is pressed upon the shoe bottom asa part of the power operation without special attention on the part ofthe operator. Accordingly all that the operator has to do under mostoperating conditions is to manipulate these two controlling members. On

the other hand, at any time when it is desirable for the operatorfurther to control the leveling roll by use of the above-mentionedtreadle, he is free to do so since there is no other member which he isrequired to control with his foot.

The above and other features of the invention, including various noveldetails of construction and combinations of parts, will now be moreparticularly described by reference to the accompanying drawings andpointed out in the claims.

The main frame 20 of the illustrated machine has pivotally connectedthereto a shoe support or jack 22 to which swinging movements areimparted by power-operated mechanism, hereinafter described, to carrythe shoe back and forth beneath a leveling roll 24 which is yieldinglyforced down on the shoe bottom to apply leveling pressure progressivelyto the sole and to which lateral tipping movements may be imparted bymeans under control of the operator to cause the leveling pressure to beapplied to the margins of the sole. The jack 22 is in many respectssimilar to the disclosure of Letters Patent No. 1,239,664, granted onSeptember 11, 1917 upon an application of W. C. Baxter, and comprises atoe post 26 fulcrumed on a short transversely extending shaft 28 mountedin suitable bearings in the frame 20 and a heel post 30 also fulcrumedon the shaft 28 and connected to the toe post by a threaded adjustingrod 32. The rod 32 is provided with oppositely threaded portions whichengage members 35, 37 pivotally connected respectively to the toe andheel posts 26, 30. Fast to the outer end of the rod 32 is a hand wheel34 fer turning the rod to move the heel post 30 toward or from the toepost and thus to vary the size adjustmentof the jack to accommodateshoes of different lengths. It will be evident that by this adjustmentthe ends of the toes of slides of different lengths are positioned insubstantially the same location. The toe and heel posts are providedwith means for supporting a shoe and last for the leveling operationcompris ing a self-adjusting toe support 36 carried by the toe post 26and a spindle 38 carried by the heel post 30, the construction beingsuch that a longlegged boot also may be supported on the jack. Thespindle 38 extends through an enlarged opening formedin a plate 40 alsocarried by the heel post 30, which plate is free to tip about an axisextending rater-any of the shoe to adjust itself to the top face of thecone of the last. This plate and the the support 36 are constructedsubstantially as disclosed in a copending application of mine, Ser. No.628,354, filed August 11, 1932, and accordingly are not described hereinin detail. The spindle 88 iscarried by a block 42 which is pivoted at 44to the top of the heel post 30 to swing in directions lengthwise of theshoe. The block 42 is connected by a link 46 to mechanism which willpresently be described whereby the block and spindle may be swung topress the toe end of the shoe firmly down upon the toe support 36.

The illustrated machine may also be provided with a saddle 48, shown inFig. 5 but omitted from the other views, for use in jacking a shoealternatively with the spindle-tipping mechanism just referred to. Thesaddle 4S, similarly to the disclosure of Letters Patent No. 1,263,361,granted on April 23, 1918 upon an application of W. C. Baxter, isconnected to the two arms of a bifurcated lever 50 by strong springs 52,and when the saddle is used the lever 50, the arms of which are pivotedat 54 to blocks slidingly mounted in slots 56 on the toe post 26, pullsit down tightly over the shoe and is then locked to a segment 58 on theheel post. The slots 56 are concentric with the shaft 28 to permitrelative movements of the toe and heel posts without disturbing therelation between the lever 50 and the heel post, as explained in thelast-mentioned Letters Patent.

The relation of the lever 50 to the spindletipping mechanism will now bedescribed. Pivo'tally connected at 60 to the heel post 30, one on eachside thereof, are links 62 the rear ends of which are connected to thearms of the lever 56 by short upwardly extending links 64. The links 62have pivotally connected thereto at 66 downwardly extending links 68which carry a horizontal pin 70 extending through a slot 72 formed in amember 74 (Figs. 1 and 5) pivoted to the lower end of the link 46.Pivotally conmay be swung up into position to serve as an abutment forthe horizontal pin 70,as shown in Figs. 1, 2 and 4, or down as shown inFig. 5. When the member 76 is in the latter positionthe pin 70 has freemovement in the slot 72 as the lever 50 is swung downwardly so that nomotion is imparted to the link 46 in operating the saddle 48. When themember 76 is in the position shown in Figs. 1, 2 and 4 downward movementof the lever 50 forces the link 46 downward to operate the spindle 38 byengagement of the pin 70 with the member 7 6. The member 7 6 is held inthe position shown in Figs. 1, 2 and 4 by a spring-press ed pin 78 whichenters a hole 80 therein (Fig. 5) The mechanism for thus rendering thelever 50 effective to operate either the saddle '48 or the link 46 isgenerally similar to the disclosure of Letters Patent No. 1,719,158,granted on July'2, 1929 upon an application of E. E. Winkley and H. A.Davenport.

In the illustrated machine the jack 22 as a whole is swung abouttheshaft 28 by a cam 90 and connections therefrom to the jack which maybe'adjusted to vary the extent of the swinging movements of the jack inaccordance with the length of the shoe being operated upon. The cam 90is formed in one side of a cam wheel 92 carried by a cam shaft 94 whichis mounted transversely in the frame 20 and is connected topower-operated means, hereinafter described, which is'continuously undermanual control and is arranged to rotate the cam wheel 92 in oppositedirections at the will of the operator to impart to the jack itsswinging movements. As shown *11 nected to the member 74 is a member 76which. 3

a spindle 132.

particularly in'Fig. 5, the toe post 26 is provided with a rearwardlyextending arm 98 connected by means of a link 100 to a rocking lever 102which is pivoted at 104 to the frame and carries at itsrear end a roll10,6 engaged by the cam 90. The arm 98 and the lever 102 are providedrespectively with segmental slots 108, 110, in which there are slidablymounted blocks 112, 114, pivotally connected to the ends, of the link100. The link 100 is pivotally connected intermediate its ends at 116 toa link 118 pivoted at 120 to the frame 20. The jack 22 is thusoscillated. by the rocking of the lever 102 about its fulcrum and itsamplitude of oscillation can be adjusted by swinging the link 100 aboutits pivot 116 to vary the effective lengthsof the arm 98 and the lever102. s

For adjusting the position of the link 100 there is provided a lever 122fulcrumed at 124 to the arm 98. Thelever 122 is connected by means of alink 126 to a downwardly extending arm 128 with which the heel post isprovidedand has pivotally connected toits upper end a member 130 inwhich there is rotatably mounted The spindle 132 is provided with arearwardly extending threaded portion which extends through a member 136pivoted on the upper end of the link 100. The spindle 132 is heldagainst lengthwise movement relatively to r the member 130 by oppositelydisposed collars 138.

The construction is therefore such that as the heel post 30 isswungabout its fulcrum 28 by movement of the threaded adjusting member 32 inaccordance with the length of the shoe to be operated upon the link 100is moved along the segmental slots 108, 110 to vary correspondingly theextent of the swinging movements of the jack. When the parts are intheirinoperative or idle positions, thesegmental slots 108, 116

j are concentric with thefulcrum 116 of the link 100 so that thisadjustment may be made without moving the toe post 26. The parts aretherefore so designed that the extent of the swinging movement impartedto the jack 22 by the cam is proportional to the size adjustment of thejack. In order further to vary the extent of the swinging movements ofthe jack to accommodate shoes ofdiflerent styles, there is providedmeans for initially adjusting the position of the link relatively to thearm 98 and the lever 102 without adjustment of the jack. As shown inFig. 5, there is rotatably mounted in the member 130 a rod 140 which isheld against lengthwise movement relatively to the member 130 by acollar 142 and a skew gear 144 which is fast on the rod 140 and theteeth of which mesh with the teeth of a skew gear 146 fast on thespindle 132. The rod 140 extends forwardly and has secured to its outerend a hand wheel 148 conveniently accessible to the operator and bymeans of which the rod and the spindle 132 may be rotated to move thelink100 along the segmental'slots 108, without disturbing the sizeadjustment of the jack.

The machine herein shown is so constructed that the leveling roll 24 ismaintained initially in a position higher than that which it occupies inoperating upon the shoe and in which also it is retracted rearwardlylengthwise of the shoe. In predetermined relation to the first rearwardswinging. movement of theijack, prior to thebe-' ginning or" suchmovement; the roll receives a forward positioning movement and is alsoswimg downwardly to. carry it into initial engagement with'the shoe onthe bottom .faceof the toe end after the jack has arrived at thelimit ofits forthe roll :24 is moved forwardly at the time and of the sole, thusinsuring against any damageto the sole or undue bending of it's marginat the toe end by contact of the roll with its edge. The roll is mountedfor turning movement on the rod 159 supported by a holder 160 and ismovable also lengthwise of the rod, springs .161 being provided at theopposite ends of the roll which normally centralize it lengthwise of therod but permit it to move in one direction or the other along the rodfor better acoommodation'to the shapes of different portions of the shoebottom. The holder 160 is a yoke-shaped1 device, portions of which areslidinglymovable lengthwise of the shoe in guideways formed in the" armsof a forked roll carrier 162 which is clamped at 164 to the forward endof a hollow shaft 166, this shaft being-mounted for turning movement inan arm 168 provided with a forked rear end fulcrurned at 170 on theframe of the machine for swinging movements heightwise of the shoe. Theholder 160 is provided with a depending lug 172 in which'there isthreaded the forward end of a rod 174 that extends rearwardly throughthe hollow shaft 166 and is connected at its rear end to a yoke 176 inwhich it is mounted 100 for turning movement. At its forward end the rod1'74 is shaped at 178 to receive a wrench by which it may be turned toadjust the holder 160 lengthwise of the shoe, the holder being held inadjusted position by a lock nut 180.105 The yoke 1'76 is connected tothe upper end of a lever 182 bya link 184, the lever being fulcrumed at186 on the frame 20, and pivotally connected to the lower end of thelever is one link 188 of a toggle, the other link 190 of which is 110pivoted to the frame. A tension spring 192 is connected at one end tothe frame 20 and at its other end to a bar 194 connected tothe kneejoint of the toggle, the spring therefore acting, when permitted, tostraighten the toggle and thereby to impart forward movement to theholder 160 and the roll 24.

The toggle is controlled by a peripheral cam 196 on the cam wheel 92through a lever 198 which is connected to the bar 194 by a rod 200. 0The lever 198 is fulcrumed-at 202. on the frame 20 and carries at itsforward end a roll- 204 (Fig. 2) engaged by the cam 196. The earn 196 isso shaped and arranged that at the beginning of the first turningmovement of the camwheel 92 from its initial position, prior to theswinging of the jack by the cam 90, it permits the spring 192 tostraighten the toggle 188, 190, and thus to move the roll 24-forwardly'to a position over the toe end or" the sole before the roll engages thesole. In the final portion of the reverse turning movement of the camwheel at the end of theoperation of the machine upon the shoe,"

ward movement, the cam 196 acts through the 35 lever198 and the rod 200to'break'the toggle and thus to move the holder 160 and the roll toaretracted position so as not to interfere with theremoval of the shoeand the mounting of another shoeon the jack.

For controlling downward swinging movement ofv the arm 168 and forraising the arm tocarry' the roll 24 upwardly away fromthe shoe there isprovided a rod 206 adjustable as to lengthand pivotally connected at 208to the above-mentioned lever 198, the rod being provided at its upperend with a head 210 arranged to engage the lower sideof the arm. It willthus be seen that as in the manner above described the downward 248(Fig. 4) and is fastened to this member by movement of the rod 206 undercontrol of the lever 198 permits the roll at the same time to be swungdownwardly by the arm 168, and when the jack is at the limit of itsfinal forward movement the roll is swung upwardly away from the shoe bythe rod 206 simultaneously with itsretractive movement lengthwise of theshoe effected by the swinging of the lever 198.

The downward swinging movement of the roll 24 which results from theabove described downward movement of the rod 206 is effected yieldinglythrough a heavy spring 214 which is connected at one end to a lever 216pivoted at 218 on the frame and at the other end to a rod 220 extendingupwardly through the head 222 of a member 224 pivotally mounted on thearm 168, the rod being secured to the head 222 by clamping nuts 226 and228. Formed on the cam wheel 92 is a peripheral cam 230 in engagementwith a roll 232 (Fig. 4) mounted on a downwardly extending arm 234 ofthe lever 216. The earn 230 thus acts through the spring 214 to pressthe roll upon the shoe bottom with the required force. The cam is soshaped that when the jack is in position for the roll to act on thedownwardly curved shank portion of the shoe bottom the lever 216 isfurther depressed, thus not only compensating for the downward curve ofthe shank, but increasing the pressure of the roll upon this portion ofthe shoe bottom, which is desirable in view of the more pronouncedtransverse curvature of the shank portion of the sole as compared withthe forepart. To limit the downward movement of the roll in case themachine is operated without any shoe on the jack, there is provided ascrew 236 on the frame arranged to serve as an abutment in engagementwith arm 168. The screw 236 is locked in adjusted position by a nut 238.

From the foregoing description it will be evident that the machine is soconstructed as to prevent excessive bending of the margin of the toe endof the sole by the roll 24, such as might otherwise result from theaction of the spring 214 on the arm 168 as the roll passes on or ofi theshoe, since the roll is always advanced to a position over the bottomface of the toe end of the sole before it engages the shoe and the jackin its forward movement never passes beyond a position in which the rollis in that relation to the sole, the roll being lifted from the shoeafter the jack has arrived in that position. The roll 24 may be tippedlaterally of the shoe at various inclinations for operating along theside edges of the shoe bottom by turning movement of thepreviously-mentioned hollow shaft 166. For this purpose there isprovided a lever 240 loosely mounted on the right-hand end of the shaft28 and connected at 244 to a' rod 246 which extends rearwardly through amember nuts 250, 252. The member 248 is pivoted on an arm 254 which isfast on one end of a shaft 260 (Fig. 3) rotatably mounted in the frame26,

the shaft having fast thereon a segmental bevel gear 264. The' gear 264engages a similar gear 266 fastened to the shaft 166 by a clamping screw268. The lever 240 is provided with a handle portion 270 extendingforwardly into a convenient position for use by the operator and bymeans of which the lever may be swung to tip the roll 24 as desired.

The construction of the machine is further such as to enable theoperator to determine selectively the portions of the shoe bottom uponwhich the leveling roll operates by control of the swinging movements ofthe arm 168. More particularly, as illustrated, the operator is enabledto swing the roll upwardly away from the shoe bottom at any time, or tohold it upraised so as not to contact with the shoe until someparticular portion of the sole is positioned under the roll. For thispurpose there is associated with the rod 220 a gripping devicecomprising a plurality of plates 272 (Fig. 2) controlled by a lever 274and provided with apertures through which the rod 220 extends. The lever274 is fulcrumed at 276 to the frame and is connected by a rod 2'78 to atreadle 280 pivoted at 202 on the frame. A spring 282 holds the treadlenormally in raised position against an adjustable stop 283. The plates272 are clamped at one end against a depending lug 284 on the lever 274by a screw 286 on the lever, while at their opposite ends they restagainst an upstanding lug 288 on the frame 20 and are pressed downwardlyagainst this lug by a spring plunger 290 on the lever 274. Normally, asshown in Fig. 2, the plates are thus positioned in such relation to therod'220 as to permit the latter to move freely upwardly or downwardthrough the apertures in the plates. If the treadle 280, however, isdepressed by the operator, the upwardswinging movement of the lever 274causes the plates to tip and thereby grip the rod 220 and thus not onlyto prevent downward movement of the rod but by further movement of the'treadle to lift the rod. The operator may thus hold the roll upraiseduntil the jack is in position for the roll to operate on the shankportion of the sole, in case it is desired to level the shank portionwithout leveling the fore-part. In operating, moreover, on shoes of thecottage shank type the operator may, after leveling one side of theshank with the roll in an inclined position, lift the roll by thetreadle and place it in an oppositely inclined position onthe other sideof the shank without engaging the central ridge of the sole. Use of thetreadle, moreover, enables the operator to lessen at any time the forcewith which the roll is pressed down upon the shoe bottom through thespring 214.

The cam wheel 92, through the operation of which the leveling roll iscontrolled automatically in the manner previously described and throughwhich swinging movements also are imparted to the jack, is operated bypower-driven means which is continuously under control of the operatorso that he may interrupt the operation of the machine at any time andmay also cause the jack to swing in one direction or the other asdesired. For this purpose the shaft 94 on which the cam wheel is mountedhas fast thereon a worm gear 292 (Fig. 6) engaged by a worm 294 on ashaft 296. The shaft 296 is driven in opposite directions at the will ofthe operator through oppositely disposed clutches 298, 300, the drivingmembers of these clutches being constantly rotated in oppositedirections and the driven members so mounted that either clutch can bemade to drive the shaft 296 at will. In the illustrated machine power isderived from a motor 362 (Figs. 1 and 3), which by means of a belt 304drives a pulley 306 fast on the outer end of a short shaft 308 journaledin the frame 20 in parallel relation to the clutch shaft 296. Looselymounted on the clutch shaft 296 in spaced relation are a pair of gears310, 312, the gear 312 being constantly rotated by a gear 314 (Fig. 9)fast on the shaft308. The gear 310 is constantly rotated in the oppositedirection through an idler gear316 (Fig. 10) which meshes with it andwith a gear318 fast on the shaft 308. The gears 316, 312 are provided,as shown, with laterally extending flanges 326, 322;:which have internalclutch surfaces and'a'ct respectively as the driving members of thevopposed clutches 298,300. Cooperating therewith are driven members 328,330 carried by a sleeve 332 which is mounted for slid- .ing movementlengthwise of the shaft 296 and is connected to the shaft by splines334. The sleeve 332 is moved lengthwise of the shaft 296 to move one orthe other of the clutch members 328, 330 into engagement with itscooperating clutch member by a lever 336 which is pivoted at 348 to theframe 26 and has pivotally connected to its upper end arod 342 whichi'sconnected at its-opposite end by means of a yoke 344 to the upper end ofan arm 346 fast on the right-hand end of a rock shaft 348 journaled inthe front of the frame 20. The lever 336 has a downwardly extendingarm'358 which is bifurcated to straddle the sleeve 332, and pivotallyconnected to the lower end of this armare blocks 352 which fitbetween'thrust washers 354, 356 mounted on the sleeve 332 between theblocks and the clutch members 328, 330. Loosely mounted on the lefthandend of the rock shaft 348 (Figs. land 2) is a lever 358 carrying at itsupper end a handle 360. The lever 358 is secured, as shown, to a secondlever 362 fast on the rock shaft 348 by means of bolts 364, 366, whichextend respectively through arcuate slots 368, 870 formed in the lever362, the construction thus being such that the lever 358 may be adjustedrelatively to the lever 362 to move the handle 360 into a convenientposition to be grasped by the hand of the operator. It will beunderstood that by the use of the handle 368 the lever 358 may be swungto'move the sleeve 332 either forwardly or rearwardly to connect eitherof the friction clutches v 238, 360, to the shaft 296, thus causing thejack 22 to be swung in either direction desired. The lever 358 is heldnormally in an idleposition with the machine at rest by equalizingsprings 374,

376 which surround the rod 342 and bear at their inner ends against 2.lug 378 on the frame 20 and at their outer ends against collars 38 6,382 fastened to the rod 342.

illustrated machine is further= provided with means for automaticallythrowing the above-described friction driving mechanism out of operationand movingthe handle 360 to its idle position the cam'wheel 92 is turnedbeyond a predeterrn... dpcint in either direction, thus insuringagainstdamage to the machine. As shown, thi means comprises a pin 384which is carried by e worm wheel 292 and is arranged to engage therearwardly extendingarm 386 of a bell-cranklever fulcrumed at 398 on theframe of the machine. This lever is provided with depending arm 392which is forkedto straddle a bushing 394 (Fig. '7), the bushing beingthreaded on the rod 342 and heldin adjusted position by a is accordinglysuch that if the cam wheel 92 is tu ed beyond a definite point in eitherdirection pin 384 engages the arm 386 and through the yieldingconnections above described. moves the rod 342 in the direction todisconnect the friction driving mechanism from the shaft 296. It will beseen that in this movement the rod 342 also acts through the arm 346 torock the shaft 348 in a direction to move the clutch-controlling lever358 and the handle 360 to idle position. v

Simultaneously with the throwing out of the friction driving mechanism,either by the abovedescribed safety device or by normal use of the handlever 358,2. brake'band410 is applied to a brake drum 412 on the shaft296 so as to-hold the shaft from further rotation. The brake band 7 theframe 20 by a bolt 418 and with a laterally extending arni42o'arrangedto be engaged by an j adjustable screw 422 carried by a lever 424 ful-'crumed at 426 on the frame of the machine. The lever 424 has pivotallyconnected to it at 428 one member 430 of afoggle the other member 432 ofwhich is pivoted at 434 to; the frame 20. The member 432 of the toggleisprovided with a pair of upwardly extending arms 436, 438 which areslotted to receive a pin 440 carried by a member 442 clamped to the rod342. I With this construction, when the rod 342 is moved in eitherdirection to disconnect the friction driving mechanism from the shaft296 the toggle member 432 is swung about its pivot 434 to straightenthetcggle. Straightening of the toggle causes the lever 424 to beswungdownwardly and through the screw 422 to apply the brake band 416 tothebrake drum412, thus holding the shaft 296 from rotaticn. When the rod242is moved in a direction to connect one or the other of theclutches298, 300,

to the shaft 296 the toggle member 432 is swung about its pivot to breakthe toggle and release the band 410 from the drum 412.

'In the operation of the machine, briefly summarized, the operatormounts a shoe on the spindle 38, turns the hand wheel 34, if necessary,

to adjust the jack tothe length of the shoe, and? then by'movement ofthe lever 50 tips the spindle 38 to clamp the shoe firmly on the toesupport 36. It will be understood that if the saddle 48 is to be used,the spindle-tippingmechanism will be disconnected from the lever 50 byturning the abutment member '26 downwardly and the shoe will be pressedfirmly against the toe. support 36 by the saddle 48 when the lever isoperated. The operator then grasps the handle 360 and by pushing upon itconnects the clutch 298 to the shaft 296t0 cause the cam wheel 92to berotated in a clockwise direction as viewed in Fig. 2. The first resultof this-movement of the cam wheel is that the'lever 198 is permitted toturn in a counterclockwise direction by its con trolling cam 196 underthe influence of the spring 192, the latter accordingly straighteningthe toggle 188, 190 to impart forward movement to the roll 24.Simultaneously the rod 206 is lowered by the lever 198, thus permittingdownward swinging movement of the arm 168 and the roll 24" under theinfluence of the spring 214. The roll is accordingly moved in aninclined path indicated diagrammatically at a in Fig. 2 so as to engagethe shoe initially upon the bottom face of the toe end of the sole insuch a location as to avoid any excessive bending of the margin of thesole, yet near enough to the end of the toe to permit proper leveling ofthe toe portionof the sole. It will be understood that the location inwhich the roll thus first engages the shoe may be variedlby adjustmentof the roll holder 160 through turning movement of the rod 174. Byreasonof the relation of the cam 196 to the jack-operating cam 90 theabove-described movement of the roll takes place prior to any movementof the jack. If the operator continues to push upon the handle 360 thecam 90 next becomes effective to impart to the jack its first rearwardmovement to cause the leveling roll to operate progressively along theshoe bottom, during which movement and thereafter during such othermovements as the jack receives the operator may, by use of the handle270, tip the roll 24 in one direction or the other at any desiredinclination for applying the proper leveling pressure to the margin ofthe sole. At any time, moreover, by control of the handle 360 theoperator may stop the movement of the jack and may throw the clutch 300into operation to reverse the direction of the movement. A plurality ofshort movements of the jack. may thus be effected while the roll isoperating upon some particular portion of the shoe bottom, such as theshank. A forward movement of the jack also may be effected to the limitdetermined by the shape of the cam 90, whereupon the operator may bringthe machine to a stop with the roll still in contact with the toe end ofthe sole and may then tip the roll to assist in properly leveling thisportion of the sole. If it. should be desired at any time to prevent theroll from operating upon some particular portion of the shoe bottom, forexample to prevent it from engaging the sole at the ball line inoperating upon shoes of certain styles or to prevent it from engagingthe sole along the central line of the shank in. operating on cottageshank shoes, the operator may lift the roll from the shoe by depressionof the treadle 280. When the leveling operation has been satisfactorilycompleted the cam wheel 92 is made to turn far enough in one directionto lift and retract the leveling roll lengthwise of the shoe, suchmovement of the roll occurring after the jack has arrived at the limitof its forward movement. The operator may then remove the shoe and mountanother one on the jack, the roll 24 occupying such a retracted positionas not to interfere in any way with these operations.
